Jar file problem

[Steve Grusak]

I have successfully created a dialog screen with four different sample graph types: XY Plot Series, Pie Chart, 3D Horizontal Bar, and an XY area plot. These are samples for now and will eventually be filled with actual data. This all works fantastically ... really cool in fact ... but only while inside of JBuilder V3.5 (yes I know it is a litle out of date). Once I create a JAR file and try to run my application outside of JBuilder I get the following error:

Exception occurred during event dispatching:
java.lang.ExceptionInInitializerError: java.lang.NullPointerException
at javax.swing.ImageIcon.<init>(Unknown Source)
at com.jrefinery.chart.JFreeChartInfo.<init>(Unknown Source)
at com.jrefinery.chart.JFreeChart.<clinit>(Unknown Source)
at com.jrefinery.chart.ChartFactory.createPieChart(Unknown Source)
at collaborate.GraphDlg.jbInit(GraphDlg.java:161)
at collaborate.GraphDlg.<init>(GraphDlg.java:49)
at collaborate.MainFrame.jbGraphs_mouseClicked(MainFrame.java:735)
.......

As far as I can tell I am including all of the com.jrefinery.* stuff in my imports as well as in the jar file. I even added the jfreechart,jcommon,and junit jars to the classpath with the same result.

I am using Java JDK1.3.1_03, jfreechart-0.9.2, jcommon-0.6.4. The Java code is included below. Would switching to the latest versions of jfreechart and jcommon correct the problem. I will be requesting the electronic doc later tonight. I hope I can get this to work because the package is very nice.

Hi Steve,
Just a suggestion: Try to download and use JFreechart 0.9.3 and JCommon 0.7.0. I think it will fix the problem.

Thanks for the suggestion Navin - unfortunately it did not help - just a different error:

THe new version of jfreechart made JBuilder complain about two deprecated methods that were being called - those were fixed - still no luck. I have ordered the doc (PDF format) - hopefully I can find the answer there ... unless anyone has any additional suggestions.

Problem fixed! I had to include the JCommonResources class to my build list. Not sure why since it is already in the JAR file. I went to the JCommon forum to find the answer which refered me to:

Thanks! The whole package is really nice.

Hi Steve,

Glad you got it resolved...thanks for posting the solution as well, it helps for anyone else who goes down the same road as yourself.

DG.
